(viii) de-icing systems;
(ix) engine-driven generators;
(x) auxiliary power unit (APU);
(xi) airborne collision avoidance system (ACAS);
(xii) terrain awareness warning system (TAWS);
(xiii) autoland systems;
(xiv) provision of crew oxygen;
(xv) supplemental oxygen for passengers.
(9) Standard operating procedures
Crew training to ensure they are familiar with normal and abnormal operating
procedures and particularly any changes regarding but not limited to:
(i) pre-flight planning;
(ii) in-flight monitoring of volcanic ash cloud affected areas and avoidance
procedures;
(iii) diversion;
(iv) communications with ATC;
(v) in-flight monitoring of engine and systems potentially affected by volcanic ash
cloud contamination;
(vi) recognition and detection of volcanic ash clouds and reporting procedures;
(vii) in-flight indications of a volcanic ash cloud encounter;
(viii) procedures to be followed if a volcanic ash cloud is encountered;
(ix) unreliable or erroneous airspeed;
(x) non-normal procedures for engines and systems potentially affected by
volcanic ash cloud contamination;
(xi) engine-out and engine relight;
(xii) escape routes; and
(xiii) operations to/from aerodromes/operating sites contaminated with volcanic
ash.
(10) Provision for aircraft technical log This should ensure:
(i) systematic entry in the aircraft technical log related to any actual or
suspected volcanic ash encounter whether in-flight or at an
aerodrome/operating site; and
(ii) checking, prior to flight, of the completion of maintenance actions related to
an entry in the aircraft technical log for a volcanic ash cloud encounter on a
previous flight.
(11) Incident reporting Crew requirements for:
(i) reporting an airborne volcanic ash cloud encounter (VAR);
(ii) post-flight volcanic ash cloud reporting (VAR);
(iii) reporting non-encounters in airspace forecast to be contaminated; and
(iv) filing a mandatory occurrence report in accordance with ORO.GEN.160.
(12) Continuing airworthiness procedures
Procedures when operating in or near areas of volcanic ash cloud contamination:
(i) enhancement of vigilance during inspections and regular maintenance and
appropriate adjustments to maintenance practices;
(ii) definition of a follow-up procedure when a volcanic ash cloud encounter has
been reported or suspected;
(iii) thorough investigation for any sign of unusual or accelerated abrasions or
corrosion or of volcanic ash accumulation;
(iv) reporting to TCHs and the relevant authorities observations and experiences
from operations in areas of volcanic ash cloud contamination;
(v) completion of any additional maintenance recommended by the TCH or by
the CAA.
(f) Reporting
The operator should ensure that reports are immediately submitted to the nearest ATS
unit using the VAR/AIREP procedures followed up by a more detailed VAR on landing
together with, as applicable, a report, as defined in Commission Regulation (EU) No
996/2010 and Regulation (EU) No 376/2014, and an aircraft technical log entry for:
(1) any incident related to volcanic clouds;
(2) any observation of volcanic ash activity; and
(3) any time that volcanic ash is not encountered in an area where it was forecast to
be.
